This post considers several aspects about improving the speed of spreadsheets in both MS Excel 2003 and 2007.

This is an upgrade from the first part in the sense that it can be adjusted to have more delay based inverters in the feedback (14).

An interactive animated demo of the gated ring oscillator in Excel 2003 based on the previous tutorial. This model stands out because of the real time schematic animation.

This is the fourth part of tutorial about making an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.

This is the third part of tutorial about making an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.

This is the second part of tutorial walking through the creation of an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.

This is the first part of tutorial explaining how to make an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.

This is the second half of the delay based Excel model tutorial. In this part the final formulas are derived and implemented in Excel 2003.

After learning how to model ideal logic gates in MS Excel 2003 it is time to attemp to create a delay based model.

This is the third part of a tutorial about modeling logic gates in MS Excel 2003. This first model includes no delay or loading for the gates.

This is the first part of a tutorial (self, 2, 3) about modeling logic gates in MS Excel 2003. This first model will include no delay or loading for the gates.

This is not a tutorial but a download post for a purely animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003.

This is the third part of a tutorial (1, 2, self) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003.

This is the second part of a tutorial (1, self, 3) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003. This part creates a very simple table type model based on combinatorial logic rather than a sequential type based on registers.

This is the first part of a tutorial (self, 2, 3) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003.
